LM2907M/NOPB

Overview

The LM2907M/NOPB is a voltage-to-frequency and frequency-to-voltage converter integrated circuit manufactured by Texas Instruments. It operates with a single power supply ranging from 6 V to 28 V. The device features a full-scale frequency of 10 kHz and an integral nonlinearity (INL) of ±1% FSR. It is housed in a 14-SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between voltage and frequency signals
• Operates on a single power supply rail
• Provides high linearity performance within specified limits

Applications

• Tachometer circuits for speed measurement
• Speed switch building blocks
• Frequency-to-voltage signal conditioning

Procurement Notes

Verify the specific suffix and package type against current datasheets, as legacy part numbers may have variations. Confirm RoHS compliance status and check for official End-of-Life notices or product change notifications before finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a single-supply operation is required for frequency modulation tasks. Ensure the input signal frequency does not exceed the 10 kHz limit. Verify that the 14-pin SOIC footprint fits the design constraints and that the ±1% FSR linearity meets the system accuracy requirements.

Part Context

This device belongs to the LM2907 family of analog special function converters. It is designed for applications requiring reliable frequency conversion without complex external components. The NOPB suffix indicates lead-free construction compliant with environmental standards.

Replacement Considerations
